Joel Sherrill 04e6f7bffb Patch rtems-rc-20000705-3.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>
that is a somewhat experimental, multilib-related patch:

  Changes:
    * Use RTEMS_ENV_RTEMSCPU instead of RTEMS_ENV_RTEMSBSP in
      configure.ins below exec/.
      At the moment, RTEMS_ENV_RTEMSCPU is more or less an optical change
      to emphasize that these subdirectories shall not depend on RTEMS_BSP
      than a real behavioral change.
    * Add AC_DEFINE_* to several aclocal/*.m4 macros to prepare
      autoheader/autoconf generated targopts.h and similiar configuration
      headers.
    * c/src/configure.in: remove exec from cfg_subdirs if multilibs are
      enabled (c/src is build per bsp, exec shall be build per cpu in c/
      or from the toplevel in future, when multilibs are enabled.)

  Notes:
    * This patch should not have any impact on the current building scheme.
    * --enable-multilib still does not work.
    * running bootstrap from the toplevel directory is required.
